[vtkusers] how to get result of the Execute Method of a subclass of vtkCommand

[Laurent PAUL]

Hi Andinet,

I agree with you, I can add methods to get the result, but, as the Execute
method is called when an event is invoked, I can not control this method.
I don't know how (and where, and when ) to call the "Get" method.
I'd want to get the result for each iteraction.

Any idea?

Laurent.
